Insights

This case series presents the first culture-proven human Lyme disease cases in Turkey, caused by Borrelia burgdorferi. The findings confirm Lyme disease presence and diverse clinical presentations in Turkey.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Clinical Medicine

Background:

  • Lyme disease, caused by Borrelia burgdorferi, is a multisystemic illness with potential chronic complications.
  • The first reported cases of Lyme disease in Turkey emerged after the 1990s, with Borrelia isolated from tick vectors.

Observation:

  • Three culture-confirmed human Lyme disease cases are presented, marking the first such instances in Turkey.
  • Case 1: A male with co-infection of Lyme disease and leptospirosis, presenting with hepatonephritis-like symptoms and pulmonary involvement.
  • Case 2: A female with Bell's palsy and a CNS lesion, where Borrelia was isolated from cerebrospinal fluid despite negative serology.
  • Case 3: A female with erythema chronicum migrans after travel to the USA, with Borrelia cultured from skin lesions.

Findings:

  • Borrelia burgdorferi was successfully cultured from all three patients, confirming Lyme disease.
  • The cases demonstrate varied clinical manifestations, including co-infection with Leptospira, neurological involvement (Bell's palsy), and dermatological signs (erythema chronicum migrans).
  • Serological tests (ELISA) were supplemented by culture for definitive diagnosis, highlighting the importance of microbiological confirmation.

Implications:

  • These findings provide the first microbiological evidence of Lyme disease in Turkey.
  • The diverse presentations underscore the need for increased awareness and diagnostic vigilance for Lyme disease in the region.
  • Further research is warranted to understand the epidemiology and clinical spectrum of Lyme disease in Turkey.
